Which medication is commonly used as a quick-relief treatment for asthma attacks?
Correct Incorrect Beta-agonist inhalers deliver medication that stimulates beta-2 adrenergic receptors in the bronchial smooth muscle, causing rapid muscle relaxation and bronchodilation. This action quickly opens narrowed airways during asthma attacks, providing prompt relief from symptoms such as wheezing, coughing, and shortness of breath. Short-acting beta-agonists (SABAs) are commonly used as rescue inhalers, whereas long-acting formulations serve as maintenance therapy to prevent exacerbations.
